'Blackbird' Vs. 'Songbird'! 'Jump' Vs. 'Vogue'! It's Day 8 of Glee's Best Performance Tourney!

Today marks the final set of battles in Round 1 of TVLine.com’s Glee All-Time Best Musical Number Bracket Tournament, and the feathers are going to be flying!

Glee Exclusive: Darren Criss and Harry Shum Jr. In, Chord Overstreet Out!

Today, you’ll have to make a tough call between two of the show’s greatest feathered friends: “Songbird” and “Blackbird,” and weigh in on a Madonna Vs. Gaga showdown (“I Love New York” vs. “Poker Face”). No, Gleeks, it won’t be easy whittling away our field of 64 down to 32, but alas that’s the first step toward settling the debate over which song-and-dance interlude ranks at No. 1 in the two-season history of Fox’s smash high-school dramedy.

Every day around 4:00 p.m. ET over the next few weeks, we’ll launch a new set of bouts that will have you mentally humming your favorite Glee moments and anxiously wondering how in the heck you’re gonna decide between ’em. So make sure the right choice is made by heading down to our polls to vote for your favorites (Round 1 voting will be open for 72 hours), and hit the comments to justify your picks.
